Rigid Motions in the Plane
Defining congruence through the lenses of translations, reflections, and rotations.
About This Topic
Defining congruence through the lenses of translations, reflections, and rotations.
Key Questions
- Differentiate which properties of a figure remain invariant under a reflection versus a translation.
- Explain how any congruence can be described as a sequence of rigid motions.
- Justify why we define congruence through motion rather than just measurement.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.
